There are plenty of mysteries surrounding Santa Claus and just how he manages to make that round-the-world trip in one night.

While part of the joy of Christmas is believing in the magic an act of kindness can bring, that doesn’t stop millions from asking the tough questions about Claus, those reindeer and how he gets down a chimney when he, shall we say, is carrying a little bit of extra weight.

Here are a few of the most asked questions about Santa and the answers you can find online.

Saint Nicholas was born in 270 AD. That would make him 1,747 years old.

How many reindeer does Santa have?

According to legend, Santa has eight reindeer – Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Dunder and Blixem. The names Dunder and Blixem are derive from Dutch words for thunder and lightning. They were later changed to Donner and Blitzen.

The names and the number of reindeer came from the 1823 poem "A Visit from St. Nicholas.” A ninth reindeer, Rudolph the Red-Nosed Reindeer, was added to the list as the popularity of the 1939 story “Rudolph the Red-Nosed Reindeer” published by the Montgomery Ward Co. grew.

How does Santa get down the chimney?

Well, we're guessing it's a very special magic that allows Santa to make it down chimneys to leave toys. One clue on how he does it may come from the poem, "A Visit from St. Nicholas." The poem mentions "a miniature sleigh and eight tiny reindeer." Does that mean Santa can miniaturize his sleigh, his reindeer, the toys and himself? It would explain a lot.
